Message: [QUOTE="96Mattman, post: 1569083, member: 41592"] I have been doing some thinking about what width my front Dually adapters should be to keep things close to stock steering geometry. Today I went out and took some measurements from the new (to me) wheels I am going to use. Here are some specs on the 05+ DRW Ford wheel: 17” x 6.5” wide Backspace is approximately 8.375” Calculated Offset: 8.375-3.25=[B]5.125” positive offset[/B] My thought was to compare the offset of the dually wheel to the offset of stock srw wheels, and make up the difference with the dually adapter. Here it goes: Stock SRW Ford wheels: 16” x 7” wide Backspace is supposedly 4.25” from what I read Calculated Offset: 4.25-3.5=[B]0.75” positive offset Calculated Dually Adapter width: 5.125”-.75”=4.375”[/B] DOES THIS MATH MAKE SENSE?! It seems own dually adapter are around 4” wide give or take .25” or so. Am I going to regret not using a wide enough adapter to keep the wheel centerline where Ford designed it to be? I am worried abou steering feel and possibility of the tires hitting the leaf springs. any input is much appreciated!!! [/QUOTE]
